This is a US Navy free balloon as used for initial lighter-than-air training during the 1920s to 1940s. It is fairly representative for a type of aircraft that first flew in 1783 and soon afterwards found a shape and construction that it retained (almost) to this day.

== Known problems ==


* [http://www.gasballooning.net/resources.htm A very good resource for information about and instructions for gas ballooning]. Has links to couple of (old but good) books available in PDF format.
* The balloon envelope shader doesn't show over MP unless the property /sim/rendering/shaders/aircraft/balloon-envelope/quality-level is manually set to 1. The property might no longer be visible in the shader settings dialog also when the ZF Navy free balloon is the user's aircraft.
